If symptoms are well controlled with moisturizers, steroids may only be required when flares occur. Corticosteroids are effective in controlling and suppressing symptoms in most cases. Once daily use is generally enough. For mild-moderate eczema a weak steroid may be used (e.g., hydrocortisone), while in more severe cases a higher-potency steroid (e.g., clobetasol propionate) may be used. In severe cases, oral or injectable corticosteroids may be used. While these usually bring about rapid improvements, they have greater side effects.

Long term use of topical steroids may result in skin atrophy, stria, telangiectasia. Their use on delicate skin (face or groin) is therefore typically with caution. They are, however, generally well tolerated. Red burning skin, where the skin turns red upon stopping steroid use, has been reported among adults who use topical steroids at least daily for more than a year.

Oatmeal contains avenanthramide (anthranilic acid amides), which can have an anti-inflammatory effect.

A number of medications speed up recovery including: tetracycline, doxycycline, and erythromycin. Erythromycin may be used as a cream. Doxycycline is most often the first antibiotic drug choice, given at a daily dosage of 100 mg for upto a month before considering tapering off or stopping. Sometimes, longer duration of low doses of doxycycline are required.

Metronidazole is less effective, is available in a gel and can be applied twice daily. If the perioral dermatitis was triggered by a topical steroid then pimecrolimus cream has been suggested as effective in improving symptoms. However, this has also been documented to cause the condition.

In persistent or especially bad rashes, an antifungal cream often has to be used. In cases that the rash is more of an irritation, a "mild" topical corticosteroid preparation, e.g. hydrocortisone cream, is used. As it is often difficult to tell a fungal infection apart from a mere skin irritation, many physicians prefer an corticosteroid-and-antifungal combination cream such as hydrocortisone/miconazole.

Multiple treatment regimes are available and treatment algorithms have been proposed.

Perioral dermatitis will usually resolve within a few months without medication and by limiting the use of cosmetics. This is called zero treatment. Topical corticosteroids should be stopped entirely if possible. If the flare proves intolerable, temporary use of a less potent topical corticosteroid can often be helpful.

Various moisture-absorbing powders, such as talcum or starch, reduce moisture but may introduce other complications. Airborne powders of any sort can irritate lung tissue, and powders made from starchy plants (corn, arrowroot) provide food for fungi and are not recommended by the American Academy of Dermatology.

One of the keys to treatment and prevention involves keeping the skin moisturized. Lotions, creams, and bath oils may help prevent an outbreak. If the condition flares up, a common treatment involves the application of topical corticosteroids. Oral antihistamines may help lessen itching. Avoidance of irritants is a common strategy. More severe cases sometimes respond to ultraviolet light treatment.

Generous application of bland emollients can improve the rash. However, complete resolution will not occur until the lip licking stops. Breaking the cycle of dryness then licking followed by more dryness is key to treatment. Sometimes, unlike in perioral dermatitis, topical steroids may be used for few days only.

If the rash does not improve or continues to spread after 2–3 of days of self-care, or if the itching and/or pain is severe, the patient should contact a dermatologist or other physician. Medical treatment usually consists of lotions, creams, or oral medications.

- Corticosteroids. A corticosteroid medication similar to hydrocortisone may be prescribed to combat inflammation in a localized area. It may be applied to the skin as a cream or ointment. If the reaction covers a relatively large portion of the skin or is severe, a corticosteroid in pill or injection form may be prescribed.

In severe cases, a stronger medicine like halobetasol may be prescribed by a dermatologist.

- Antihistamines. Prescription antihistamines may be given if non-prescription strengths are inadequate.

Topical corticosteroids, such as hydrocortisone have proven themselves effective in managing AD. If topical corticosteroids and moisturisers fail, short-term treatment with topical calcineurin inhibitors like tacrolimus or pimecrolimus may be tried, although they are usually avoided as they can increase the risk of developing skin cancer or lymphoma. Alternatively systemic immunosuppressants may be tried such as ciclosporin, methotrexate, interferon gamma-1b, mycophenolate mofetil and azathioprine. Antidepressants and naltrexone may be used to control pruritus (itchiness). In 2016 crisaborole was approved as a topical treatment for mild-to-moderate eczema. In 2017, the biologic agent dupilumab was approved to treat moderate-to-severe eczema.

A more novel form of treatment involves exposure to broad or narrow-band ultraviolet (UV) light. UV radiation exposure has been found to have a localized immunomodulatory effect on affected tissues and may be used to decrease the severity and frequency of flares. In particular, the usage of UVA1 is more effective in treating acute flares, whereas narrow-band UVB is more effective in long-term management scenarios. However, UV radiation has also been implicated in various types of skin cancer, and thus UV treatment is not without risk.

Id reactions are frequently unresponsive to corticosteroid therapy, but clear when the focus of infection or infestation is treated. Therefore, the best treatment is to treat the provoking trigger. Sometimes medications are used to relieve symptoms.These include topical corticosteroids, and antihistamines. If opportunistic bacterial infection occurs, antibiotics may be required.

A full recovery is expected with treatment. Recurrent id reactions are frequently due to inadequate treatment of the primary infection or dermatitis and often the cause of recurrence is unknown.

The clinical expression of the dermatitis can be mitigated by avoidance of the allergen. Through compliance with avoidance measures, the immune system can become less stimulated. The key to avoidance is proper evaluation and detection of the inciting allergen. However, once the immune system registers the allergen, the recognition is permanent.

The first step in treating the condition is appropriate recognition of the clinical problem, followed by identification of the culprit chemical and the source of that chemical. Corticosteroid creams should be used carefully and according to the prescribed directions because when overused over longer periods of time they can cause thinning of the skin. Also, in some instances such as poison ivy dermatitis calamine lotion and cool oatmeal baths may relieve itching.

Usually, severe cases are treated with systemic corticosteroids which may be tapered gradually, with various dosing schedules ranging from a total of 12 – 20 days to prevent the recurrence of the rash (while the chemical allergen is still in the skin, up to 3 weeks, as well as a topical corticosteroid. Tacrolimus ointment or pimecrolimus cream can also be used additionally to the corticosteroid creams or instead of these. Oral antihistamines such as diphenhydramine or hydroxyzine may also be used in more severe cases to relieve the intense itching. Topical antihistamines are not advised as there might be a second skin reaction (treatment associated contact dermatitis) from the lotion itself.

The other symptoms caused by allergic contact dermatitis may be eased with cool compresses to stop the itching. It is vital for treatment success that the trigger be identified and avoided. The discomfort caused by the symptoms may be relieved by wearing smooth-textured cotton clothing to avoid frictional skin irritation or by avoiding soaps with perfumes and dyes.

Commonly, the symptoms may resolve without treatment in 2 to 4 weeks but specific medication may hasten the healing as long as the trigger is avoided. Also, the condition might become chronic if the allergen is not detected and avoided.

There are 4 aspects to the treatment of angular cheilitis. Firstly, potential reservoirs of infection inside the mouth are identified and treated. Oral candidiasis, especially denture-related stomatitis is often found to be present where there is angular cheilitis, and if it is not treated, the sores at the corners of the mouth may often recur. This involves having dentures properly fitted and disinfected. Commercial preparations are marketed for this purpose, although dentures may be left in dilute (1:10 concentration) household bleach overnight, but only if they are entirely plastic and do not contain any metal parts, and with rinsing under clean water before use. Improved denture hygiene is often required thereafter, including not wearing the denture during sleep and cleaning it daily. For more information, see Denture-related stomatitis.

Secondly, there may be a need to increase the vertical dimension of the lower face to prevent overclosure of the mouth and formation of deep skin folds. This may require the construction of a new denture with an adjusted bite. Rarely, in cases resistant to normal treatments, surgical procedures such as collagen injections (or other facial fillers such as autologous fat or crosslinked hyaluronic acid) are used in an attempt to restore the normal facial contour. Other measures which seek to reverse the local factors that may be contributing to the condition include improving oral hygiene, stopping smoking or other tobacco habits and use of a barrier cream (e.g. zinc oxide paste) at night.

Thirdly, treatment of the infection and inflammation of the lesions themselves is addressed. This is usually with topical antifungal medication, such as clotrimazole, amphotericin B, ketoconazole, or nystatin cream. Some antifungal creams are combined with corticosteroids such as hydrocortisone or triamcinolone to reduce inflammation, and certain antifungals such as miconazole also have some antibacterial action. Diiodohydroxyquinoline is another topical therapy for angular cheilitis. If "Staphylococcus aureus" infection is demonstrated by microbiological culture to be responsible (or suspected), the treatment may be changed to fusidic acid cream, an antibiotic which is effective against this type of bacteria. Aside from fusidic acid, neomycin, mupirocin, metronidazole, and chlorhexidine are alternative options in this scenario.

Finally, if the condition appears resistant to treatment, investigations for underlying causes such as anemia or nutrient deficiencies or HIV infection. Identification of the underlying cause is essential for treating chronic cases. The lesions may resolve when the underlying disease is treated, e.g. with a course of oral iron or B vitamin supplements. Patch testing is recommended by some in cases which are resistant to treatment and where allergic contact dermatitis is suspected.

You have to treat the primary cause or the exacerbation may persisist and reincide.

Topical steroids are the primary category of medications used to treat exfoliative dermatitis (ED). A sedative antihistamine may be a useful adjunct for pruritic patients, since it helps patients to sleep at night, thus limiting nocturnal scratching and excoriations. Antimicrobial agents often are used if an infection is suspected to be precipitating or complicating exfoliative dermatitis. Other drugs specifically indicated for management of underlying cause of exfoliative dermatitis may be necessary.

In an industrial setting the employer has a duty of care to its worker to provide the correct level of safety equipment to mitigate exposure to harmful irritants. This can take the form of protective clothing, gloves, or barrier cream, depending on the working environment.

Topical antibiotics should not be used to prevent infection in wounds after surgery. When they are used, it is inappropriate, and the person recovering from surgery is at significantly increased risk of developing contact dermatitis.

Treatment may include corticoids, astringents, and keratolytics. Dermatoses tend to be recurrent unless the use or contact can be avoided. Discontinuation of the instrument is curative in almost all cases, but usually impractical.

Dapsone is an effective treatment in most people. Itching is typically reduced within 2–3 days. However, dapsone treatment has no effect on any intestinal damage that might be present.

Therefore, a strict gluten-free diet must also be followed, and this will usually be a lifelong requirement. This will reduce any associated intestinal damage and the risk of other complications. After some time on a gluten-free diet, the dosage of dapsone can usually be reduced or even stopped, although this can take many years.

Dapsone is an antibacterial, and its role in the treatment of DH, which is not caused by bacteria, is poorly understood. It can cause adverse effects on the blood, so regular blood monitoring is required.

Dapsone is the drug of choice. For individuals with DH unable to tolerate dapsone for any reason, alternative treatment options may include the following:

- colchicine

- lymecycline

- nicotinamide

- tetracycline

- sulfamethoxypyridazine

- sulfapyridine

Antihistamines are used primarily to reduce itching, if present. However, research studies suggest that some antihistamines have anti-inflammatory properties.

Topical 5-fluorouracil (5-FU, Efudex, Carac) has been shown to be an effective therapy for diffuse, but minor actinic cheilitis. 5-fluorouracil works by blocking DNA synthesis. Cells that are rapidly growing need more DNA, so they accumulate more 5-fluorouracil, resulting in their death. Normal skin is much less affected. The treatment usually takes 2–4 weeks depending on the response. The typical response includes an inflammatory phase, followed by redness, burning, oozing, and finally erosion. Treatment is stopped when ulceration and crusting appear. There is minimal scarring. Complete clearance has been reported in about 50% of patients.

Imiquimod (Aldara) is an immune response modifier that has been studied for the treatment of actinic cheilitis. It promotes an immune response in the skin leading to apoptosis (death) of the tumor cells. It causes the epidermis to be invaded by macrophages, which leads to epidermal erosion. T-cells are also activated as a result of imiquimod treatment. Imiquimod appears to promote an “immune memory” that reduces the recurrence of lesions. There is minimal scarring. Complete clearance has been demonstrated in up to 45% of patients with actinic keratoses. However, the dose and duration of therapy, as well as the long-term efficacy, still need to be established in the treatment of actinic cheilitis.

The topical antifungal medications ketoconazole and ciclopirox have the best evidence. It is unclear if other antifungals are equally effective as this has not been studied.

Most cases of angular cheilitis respond quickly when antifungal treatment is used. In more long standing cases, the severity of the condition often follows a relapsing and remitting course over time. The condition can be difficult to treat and can be prolonged.

Shampoos use a combination of special ingredients to control dandruff.

Antifungal treatments including ketoconazole, zinc pyrithione and selenium disulfide have been found to be effective. Ketoconazole appears to have a longer duration of effect.

Ketoconazole is a broad spectrum antimycotic agent that is active against "Candida" and "M. furfur". Of all the antifungals of the imidazole class, ketoconazole has become the leading contender among treatment options because of its effectiveness in treating seborrheic dermatitis as well.

Ciclopirox is widely used as an anti-dandruff agent in most preparations.
